Howard Marks Warns Against AI Hype and Bubble Risks as AI Stocks Decline in 2025
The chipmaker Nvidia Corp., along with other stocks tied to artificial intelligence and related exchange-traded funds, has experienced a significant drop in value during 2025. Despite the persistent excitement surrounding the artificial intelligence sector, this decline has led to concerns about possible market bubbles.
What Happened: In early January, Howard Marks, who is the co-founder and co-chairman of Oaktree Capital Management, released his latest memo titled ‘On Bubble Watch’. In a podcast episode called ‘Behind the Memo – On Bubble Watch’ with Harry Whitelaw, Marks discussed how artificial intelligence is set to revolutionize various industries. He highlighted that the novelty and excitement surrounding AI have created an environment without any historical precedent.
He noted, “That’s a great precursor for the kind of enthusiasm that sometimes leads to bubbles.” Marks pointed out that the combination of excitement for innovations and the fear of missing out is a powerful driver that he has observed repeatedly throughout his career.
This cautionary outlook is reflected in the poor performance of AI-related stocks and sectors throughout 2025. Although new technologies like DeepSeek are anticipated to boost demand for AI, the overall weakness in the sector is obvious following the exuberance seen in 2024.
